preferably high carbon steel stock, one end of" which, designed to constitutethe rear end of the runner, is shown in Fig. 2 as it appears after the stockhas been out off to the required length. In carrying out our invention, we first remove the web 2 from this extremity of the stock inwardly for a distance preferably a little greater than the height of the'web, and then bevel the The stock having been prepared as just de- 4 of the web, and finally pinching or crimping the corners of the flange which now project for wardly on op'posite sides of the saidedge down wardly and: inwardly, against or substantially against the web approximately as shown in Fig. 5, thus completingthe finishing of the rear end 1' of the runner. With most classes of stock, this bending up of the. portion 2' of the ilange and the crimping of its marginalportions or front corners down on opposite sides of thewebf p V v n and a yerticaiweb, the flange extending beyond can best be performed whilelthe stock' islheated and with the aid of a. die or fixture so as to produce a neat and symmetrical job, but the particu inabove described, presents no sharp corners or project-time oifa character likely to cause injury to a userof the sled although entirely capable of being readily thrust into the ground or snow I with a minimmnofeifort'w'hen it is desired'to stand the sled in a substantially vertical position while the extremity of the web is strengthened and afforded effective lateral support} Moreover-{our method of; finishing runner end presents no' maior diificulties from a manufac provided a runner endflnish which meets; the requirements of both the user and the sled manufacturer, while devoid :of the; objections which have been'iriherent, far as we areaware; in the various e'ndfinishes heretofore proposed or the rear ends of inverted V r section-sled runners for the purpose of protecting t'heusers of the sleds. from bodily injury.
